Extrusion is a process widely used in the polymer processing industry. It involves pushing material through a die with a specific cross-sectional shape, resulting in products like profiles, thin ...

Reactive processing in polymer extrusion harnesses the extruder as a continuous reactor, enabling in situ chemical modification of polymers while they are conveyed and melted. By integrating ...

Scientists at Oak Ridge National Laboratory have developed a vacuum-assisted extrusion method that reduces internal porosity—by up to 75%—in large-scale 3D-printed polymer parts. The paper is ...

Changes such as the transition from crystalline to amorphous phases or shifts in vibrational modes can be used to customize the end-polymer's mechanical, thermal, and optical properties to specific ...

Polymer extrusion is a cornerstone of modern manufacturing, employed to produce films, pipes, profiles and advanced composites at industrial scale. The mechanical properties of extruded ...

Editor?s note: Chris Rauwendaal is a designer, consultant, and seminar instructor who has written extensively on process engineering and extrusion topics. Part 1 of this article (PM&A Nov./Dec. 2002) ...

Researchers at Lawrence Livermore National Laboratory (LLNL) have modernized high-explosive (HE) manufacturing by adapting ...

While countless tubes are extruded or injection molded each year, these manufacturing techniques are neither the most optimal nor the most cost-effective methods available to medical device ...

Extrusion technology eliminates manual assembly operations, reduces inventory costs, and enables just-in-time production for ...

Increasingly smaller medical devices require tighter tolerances that make extrusion process control more difficult. Photos courtesy of TEEL PLASTICS INC. As medical devices get smaller and tolerances ...

With its diverse portfolio of polymer testing and sensing equipment, Dynisco is bringing rheology to the masses. Rheology is the investigation of the ­flow and deformation behavior of materials when ...
